Planet Earth: Frozen Planet II

Coming face to face with the scientists bearing witness to history's profound climate shift; pondering the effect these changes have on Earth's human and animal communities, mapping the destruction from space and learning how to save the planet.

Going back to the far North of the planet where the largest landhabitat on Earth exists, home to great Boreal forests and the barren tundra.

Trekking across the planet's most hostile frozen zone: Antarctica; getting to know ice.

Found on every continent, mountains create unique frozen worlds, home to extraordinary animals that must overcome the crushing conditions of the cold.

At the top of the planet lies the Arctic Ocean; after four months of winter darkness, the sun returns to reveal a frozen ocean covered in ice; mother polar bears emerge from their hillside dens and lead their cubs down to the sea ice to hunt.
